Operation panel: 7-inch color touch screen display input, temperature curve recording
Control system: standard: single-chip controller, position setting to open and close the cooling temperature difference Option: Siemens S7 series PLC and module
Fully enclosed system: The whole system is a fully enclosed system. The low temperature does not absorb the moisture in the air. The system does not increase the pressure due to high temperature during operation, and the heat medium is automatically replenished at low temperature.
Circulating pump: Wuxi Guanya magnetic drive pump / optional German brand magnetic drive pump
Evaporator: Danfoss / High Force Plate Heat Exchanger
Condenser: Casing type water-cooled condenser / tube-type water-cooled condenser
Intermediate heat exchanger: Danfoss / high force plate heat exchanger
Refrigeration accessories: oil separator, drying filter, expansion valve, refrigeration solenoid valve, pressure control, sight glass, etc. are all adopted by Emerson / Danfoss and other brands
Electrical AC contactors, intermediate relays, circuit breakers, thermal relays, etc. choose Schneider / ABB brand
Refrigerant: R404A / R23 mixed refrigerant
Coolant: non-corrosive liquid, ethanol aqueous solution, heat transfer oil, etc.
Safety protection: high voltage protection, water cut protection, over current protection, leakage protection, continuous and phase failure protection, high temperature protection, sensor failure, low level alarm and other multiple safety protection
Level indication: using glass level indication
Pipe material: expansion tank, cold storage tank, circulation pipeline are all SUS304
